Overview

The oil and gas sector is the largest energy producer in the U.S., responsible for about 74% of primary energy production. (DOE EIA) 

The industry is structured into three segments:

  • Upstream - focuses on oil and gas exploration, extraction, and production of crude oil and natural gas from underground wells or from surfaces shales and tars (NAICS 211).
  • Midstream - involves gathering, storing, and transporting oil and natural gas via pipelines, rail, tankers, and trucks. (Various NAICS 48 subsectors)
  • Downstream - operations engaged in processing and refining (NAICS 32411) crude oil into refined petroleum products (gasoline, diesel, lubricants, asphalt binders, etc.) and processing and purifying natural gas for distribution to customers.

All three segments of the oil & gas industry have regulatory responsibilities under different EPA programs offices. Other federal agencies with regulatory oversight include the Federal Energy Regulatory Commission, U.S. Department of the Interior Bureau of Land Management,  and U.S. Department of Transportation Pipeline and Hazardous Materials Safety Administration.
